Dry ice blasting gun with adjustable handle

Abstract

A hand-held blasting gun for use in dry ice blasting for cleaning purposes. A handle and a nozzle mount are pivotally joined so a nozzle on the nozzle mount can be adjustably directed relative to the handle. A flexible hose is fitted in the gun, extending from the end of the handle to the nozzle so as to send without kinking.

We claim:  
     
       1. A hand-held blasting gun for directing a blasting stream of dry ice particles and a carrier of gas, said blasting gun comprising: 
       a handle adapted to be held in an operator's hand, and having a first end and a second end;  
       an actuating switch on said handle engageable by the operator;  
       a nozzle mount;  
       a pivot pivotally joining the second end of said handle to said nozzle mount, whereby the angle between them can adjustably be varied;  
       a nozzle removably mounted to said nozzle mount;  
       a flexible hose passing through said handle and said nozzle mount having one end to be connected to a source of said blasting stream, and the other connected to said nozzle mount and by it to said nozzle;  
       said hose passing inside said handle at its said first end, and being protected from exposure by said handle and nozzle mount.  
     
     
       2. Apparatus according to  claim 1  in which guide surfaces inside said gun at said pivot prevent the hose from kinking. 
     
     
       3. Apparatus according to  claim 1  in which said nozzle mount includes a connector with a bayonet coupler to which a nozzle can be removably attached. 
     
     
       4. Apparatus according to  claim 1  in which a light is provided in said nozzle mount facing in the direction of the nozzle, and encircling the nozzle mount. 
     
     
       5. Apparatus according to  claim 1  in which said pivot includes means releasably to hold the adjustment of the handle and the nozzle mount. 
     
     
       6. Apparatus according to  claim 2  in which said nozzle mount includes connection with a bayonet coupler to which a nozzle can be removably attached. 
     
     
       7. Apparatus according to  claim 6  in which a light is provided in said nozzle mount facing in the direction of the nozzle, and encircling the nozzle mount. 
     
     
       8. Apparatus according to  claim 7  in which said pivot includes means releasably to hold the adjustment of the handle and the nozzle mount.
